的OutOfMemoryError在KXmlParser

Question

我從服務器獲取數據：

HttpTransportSE androidhttpTranport = new HttpTransportSE(URL, ContantSystem.TimeOut); 
androidhttpTranport.call(SOAP_ACTIONS, envelope); 
Object responseBody = responseBody = envelope.getResponse(); 

我的應用程序顯示了一個exceiption：

我的數據是大約2.4MB（5.000.000個字符）。我的設備的內存是否有限制？爲什麼？

Answer 1

內存限制是針對整個應用程序，而不是僅針對http。所以你有很多內存在應用程序的其他地方使用，或者你的手機整體的內存很低。儘管它很可能是你的應用程序。在您的應用程序中運行hprof並查看您是否泄漏了引用。相信大型Java程序中的內存管理與C++一樣需要儘可能多的努力，並且Android的框架可以很容易地將大量傳遞給它的對象像活動一樣泄漏出去。
